Python has builtin functions for common tasks from "summary" of Python For Dummies by Stef Maruch,Aahz Maruch
Python is designed to make your life easier. One way it does this is by providing you with a set of built-in functions for common tasks. These functions are ready to use right out of the box, so you don't have to reinvent the wheel every time you need to perform a common operation. For example, if you need to find the length of a string, you can use the len() function. This function takes a string as input and returns the number of characters in that string. So instead of writing a loop to count the characters yourself, you can simply call the len() function and get the result in one line of code. Similarly, Python provides a built-in function called max() that can be used to find the largest element in a list. This function takes a list as input and returns the maximum value in that list. Again, this saves you th...
